Clean Truck Check Database | Your Resource for California Truck Owners

The Clean Truck Check Database (CTC-VIS)

The CTC-VIS (Clean Truck Check - Vehicle Inspection System) is a key aspect of staying compliant with the CARB HD I/M program because it serves as the official platform for submitting and tracking emissions test results. For vehicle owners, registration in CTC-VIS ensures they receive compliance notifications and can verify their fleet’s status, avoiding penalties. For certified testers, setting up a CTC-VIS account before testing is essential, as all OBD and smoke opacity test results must be submitted through the system for the vehicle to remain compliant. Without access to CTC-VIS, a tester cannot officially report results, which means the vehicle’s compliance status will not be updated, potentially leading to fines for the owner. Therefore, registering in CTC-VIS before offering testing services is a necessary step to ensure a smooth, legal operation.
